The Metallicity Dependence of the High-Mass X-ray Binary Luminosity Function

Bret D. Lehmer, Rafael T. Eufrasio, Antara Basu-Zych +7

We present detailed constraints on the metallicity dependence of the high mass X-ray binary (HMXB) X-ray luminosity function (XLF). We analyze ~5 Ms of Chandra data for 55 actively…

Evidence in favour of density wave theory through star formation history maps and spatially resolved stellar clusters

Shameer Abdeen, Daniel Kennefick, Julia Kennefick +7

Stationary Density Wave Theory predicts the existence of an age gradient across the spiral arms with a phase crossing at the co-rotation radius. Using star formation history (SFH)…

Chandra reveals a luminous Compton-thick QSO powering a blob in a starbursting protocluster

Fabio Vito, William Nielsen Brandt, Bret Darby Lehmer +7

Galaxy clusters in the local universe descend from high-redshift overdense regions known as protoclusters. The large gas reservoirs and high rate of galaxy interaction in protoclus…

A census of ultraluminous X-ray sources in the local Universe

Konstantinos Kovlakas, Andreas Zezas, Jeff J. Andrews +5

Using the Chandra Source Catalog 2.0 and a newly compiled catalogue of galaxies in the local Universe, we deliver a census of ultraluminous X-ray source (ULX) populations in nearby…

X-ray Binary Luminosity Function Scaling Relations in Elliptical Galaxies: Evidence for Globular Cluster Seeding of Low-Mass X-ray Binaries in Galactic Fields

Bret D. Lehmer, Andrew P. Ferrell, Keith Doore +10

We investigate X-ray binary (XRB) luminosity function (XLF) scaling relations for Chandra detected populations of low-mass XRBs (LMXBs) within the footprints of 24 early-type galax…

The Environment of Lyman Break Analogues (ELBA) survey: Star-forming galaxies in small groups

L. Santana-Silva, T. S. Gonçalves, A. Basu-Zych +7

The Environment of Lyman Break Analogues (ELBA) survey is an imaging survey of 33 of the southern sky. The survey was observed in {\it u}, {\it g}, {\it r}, and {\it i} b…

Determining the Co-Rotation Radii of Spiral Galaxies Using Spiral Arm Pitch Angle Measurements at Multiple Wavelengths

Shameer Abdeen, Daniel Kennefick, Julia Kennefick +4

The spiral arms spanning disk galaxies are believed to be created by density waves that propagate through galactic disks. We present a novel method of finding the co-rotation radiu…
